HAMMER2 and fsck for review

HAMMER2 is Copy on Write, meaning changes are made to copies of existing data.  This means operations are generally atomic and can survive a power outage, etc.  (You should read up on it!)  However, there's now a fsck command, useful if you want a report of data validity rather than any manual repair process.
